Phase 16 of the Klaerungen / risk-assessment polish. Sources from
EN ISO 12100 Anhang B Tabelle B.1 are now first-class:
A) HazardPattern.ISO12100Section identifier (string), persisted only as
the section number (e.g. "6.3.5.5") — not the norm text. Keeps the
library urheberrechtlich neutral (DIN/Beuth license). 57 patterns
labeled today; rest will follow on touch.
B) Category split per ISO 12100 Nr. 4 vs Nr. 5:
- 16 patterns reclassified noise_vibration -> noise_hazard
- 7 patterns reclassified noise_vibration -> vibration_hazard
- 1 pattern (HP228 UV-/Laermexposition) kept multi-cat
acceptableMeasureCategories now accepts both new aliases plus the
legacy noise_vibration. Coverage test recognises both as valid.
C) 5 new ISO-12100-Annex-B gap patterns (HP1900-HP1904):
- HP1900 Vakuum-Verletzung (6.3.5.5)
- HP1901 Federenergie / elastische Elemente (6.2.10)
- HP1902 Rutschen/Stolpern auf rauer Oberflaeche (6.3.5.6)
- HP1903 Hochdruckinjektion (6.3.5.4) — includes clarifying
"no hand-locating of leaks" question
- HP1904 Ersticken durch Brustkorbquetschung (6.3.5.2)
The library now mirrors the ISO 12100 Annex B structure for the gaps
the Bremse benchmark surfaced.

Two-part nachhaltiger fix replacing the previous "fill to 5 mitigations
no matter what" behavior that the GT-Bremse benchmark proved
unfaithful (e.g. HP1625 "scharfe Kanten" returning M005 "Rotations-
bewegung vermeiden" via category fallback; HP1651 "Wiederanlauf
Roboter" returning M054 "Sichere thermische Auslegung" via
mismatched pattern reference).
PART A — Set-based category filter (handlers package):
- acceptableMeasureCategories: replaces 1:1 patternCatToMeasureCat
with a curated set per pattern category, so e.g.
safety_function_failure now accepts software_control measures
(watchdogs, plausibility checks) and emc_hazard accepts both
electrical and software_control measures
- isCategoryCompatible: gate every measure id against the accepted
set before creating a mitigation; mismatches log MEASURE-SKIP
- The old category fallback is REMOVED. A hazard whose pattern has
no category-compatible measure is now created with zero mitigations
and logged as COVERAGE-GAP — the operator must consult an expert.
No more silent invention of generic defaults.
PART B — 235 pattern author-error fixes across 26 files:
- HP040-HP044 (AI): M101/M102/M103 (Auffangwanne/Absauganlage) ->
M133 Anomalieerkennung + M214 Plausibilitaet + M213 Sensor-Redundanz
+ M044 Zweikanalige Steuerung + others
- HP011-HP015, HP104-HP109, HP1085-HP1095, HP1281-HP1334 (electrical):
M001-M005/M054/M061 placeholders -> M481/M482 Isolation +
M511-M522 PE/Schutzleiter/RCD/Hauptschalter
- HP110-HP1331 (material_environmental): M101-M103 -> M384-M395
Brandschutz/Laserschutz + M533/M408 SDB/PSA
- HP800-HP858, HP1178-HP1264 (software/sensor/hmi):
M101/M104 -> M105/M106/M107/M214 SPS/Watchdog/Plausibilitaet
- HP026, HP611-HP1690 (ergonomic): M001/M082 -> M353-M360 +
M530-M532 Hebehilfe/ergonomische Hoehe
- HP201-HP1697 (mechanical): M054/M051 -> M002/M008/M061/M141 +
M487/M488 Tueroeffnung-Stillsetzung/Wiederanlauf
- Plus EMF/Strahlung/Brand/Lärm/Vibration/Kommunikation/Cyber
Coverage shift (Pattern-Author-Fehler bei aktiviertem Set-Filter):
start: 237 patterns with zero category-compatible measures
after Stufe 1A: 5 (AI)
after Stufe 1B: 20 (mechanical Bestand)
after Stufe 1C: 35 (electrical Bestand)
after Stufe 1D: 29 (material_environmental)
after Stufe 1E: 29 (software/sensor/hmi)
after Stufe 1F: 20 (ergonomic)
after Stufe 1G: 80 (thermal/comm/radiation/fire/safety)
final: 0 (28 extended.go/extended2.go duplicates fixed)
New regression tests:
- TestEveryPattern_HasCategoryCompatibleMeasure: every pattern in
collectAllPatterns() must reference at least one category-compatible
measure; gaps must be explicitly listed in AllowlistKnownGaps
(currently empty). Fails CI for any new pattern that drifts.
- TestAcceptableMeasureCategories: pins the set-mapping for the
7 most-bug-prone pattern categories.
- TestIsCategoryCompatible_EmptyMeasureCat: protects legacy entries.
A separate task #11 tracks 58 HP-ID duplicates between
extended.go/extended2.go and cobot.go/press.go/operational.go —
patterns are semantically different and TestGetBuiltinHazardPatterns_-
UniqueIDs misses them because it only checks HP001-HP044.

Patterns for playground, escalator, wind turbine, glass washing,
laundry, crane, lathe, rotary transfer, press now require matching
MachineTypes — they no longer fire for unrelated projects.
Neutralized zone texts in base patterns HP006/HP008 (removed
"Pressenraum", "Kran-/Hebezeugbereich").
Fixes: Spielplatz, Fahrtreppe, Windturbine etc. appearing in robot cell.
